Eye-soothing Externally-applied Liquid Medicine and Preparation Method Therefor

A method for preparing an eye-soothing externally-applied liquid medicine, comprising the following steps:

• S01:
• accurately weighing a water phase:
• 84.993 g of purified water, 0.1 g of atropine, 0.5 g of a cassia seed extract, 0.5 g of a mulberry leaf extract, 0.2 g of a marigold flower extract, 0.5 g of a fibs albiziae extract, 0.5 g of an eyebright extract, 0.2 g of a radix codonopsis extract, 0.2 g of a common foxglove leaf extract, 0.5 g of a semen cuscutae extract, 0.5 g of a celosiae semen extract, 0.5 g of a flos buddlejae extract, 0.5 g of vitamin B1, 0.005 g of vitamin B2, 0.001 g of vitamin B12, 0.5 g of adenosine triphosphate, 0.1 g of sodium hyaluronate, and 0.1 g of exopolysaccharide;
• S02:
• accurately weighing an oil phase:
• 6 g of hydrogenated castor oil, 1 g of cetyl ethyl hexanoate, 1 g of vaccinium myrtillus seed oil, 1 g of vitamin A, and 0.001 g of lutein;
• S03:
• accurately weighing an additive phase:
• 0.6 g of phenoxyethanol;
• S04:
• mixing all the components in the water phase to obtain a first mixture and then stirring the first mixture until the first mixture is dissolved, and heating the first mixture up to 50° C.-95° C., preferably 60° C.-90° C., and more preferably 70° C.-80° C.;
• S05:
• mixing all the components in the oil phase to obtain a second mixture and then evenly stirring the second mixture, and heating the second mixture up to 5020 C.-95° C., preferably 60° C.-90° C., and more preferably 70° C.-80° C., wherein a first speed range of stirring is 200 rpm-2500 rpm, preferably 300 rpm-1500 rpm, and more preferably 300 rpm-1000 rpm;
• S06:
• under a condition of stirring or homogenizing, slowly adding the oil phase into the water phase to obtain a third mixture, and stirring the third mixture for 5 min-30 min, wherein a second speed range of stirring is 200 rpm-2500 rpm, preferably 300 rpm-2000 rpm, and more preferably 300 rpm-1500 rpm, and during stirring, a first temperature is 50° C.-95° C., preferably 60° C.-90° C., and more preferably 70° C.-80° C.;
• and
• S07:
• stirring the third mixture at a reduced speed, and then cooling the third mixture down to 30° C.-50° C.;
• finally adding the additive phase into the third mixture to obtain a fourth mixture;
• and stirring the fourth mixture until room temperature to obtain the eye-soothing externally-applied liquid medicine, wherein a third speed range of stirring is 200 rpm-600 rpm.
